Laser cutting device for metal cutting

Abstract

The invention relates to a laser cutting device for metal cutting. The laser cutting device comprises a support, transverse supports arranged on the support and a longitudinal support. The longitudinal support is arranged in slideways of the transverse supports. The bottom end of the longitudinal support is provided with a focusing field lens. The focusing field lens can move along the longitudinal support. The two ends of the longitudinal support are fixedly arranged on the transverse supports through fixed columns. A laser device is arranged on one side of the focusing field lens. A conveying device is arranged on the other side of the focusing field lens. The conveying device comprises conveying rollers and a conveyor belt arranged on the conveying rollers. The two sides of the conveyorbelt are provided with limiting plates for preventing parts to be cut from falling off. The longitudinal support moves along the transverse supports to drive the focusing field lens to move. The focusing field lens can move on the longitudinal support. The longitudinal support moves up and down along the fixed columns to drive the focusing field lens to move up and down. Accordingly, omni-directional movement of the focusing field lens in the height, longitudinal and transverse directions is realized so that an output laser beam can conduct cutting in multiple dimensionality directions of a material.

Description

technical field [0001] The invention relates to a laser cutting device, in particular to a laser cutting device for metal cutting. Background technique [0002] The laser has the characteristics of good parallelism and high energy. It is often used in the field of cutting and processing. The laser cutting machine used now often places a condenser lens in front of the light source system to focus the parallel laser light generated by the light source system into one point. Because of this The energy of the focus point is extremely high, so the focus is used for cutting and processing, but the condenser lens of the existing laser cutting machine cannot be replaced, and the cutting energy required for different metal cutting parts is different, and the energy is too large or too small. To achieve a good cutting effect, it is difficult to meet the demand only by changing the intensity of the light source. [0003] However, most assembly lines, including metal material laminatin...

[0002] The laser has the characteristics of good parallelism and high energy. It is often used in the field of cutting and processing. The laser cutting machine used now often places a condenser lens in front of the light source system to focus the parallel laser light generated by the light source system into one point. Because of this The energy of the focus point is extremely high, so the focus is used for cutting and processing, but the condenser lens of the existing laser cutting machine cannot be replaced, and the cutting energy required for different metal cutting parts is different, and the energy is too large or too small. To achieve a good cutting effect, it is difficult to meet the demand only by changing the intensity of the light source

[0003] However, most assembly lines, including metal material laminating lines, can only be fixedly configured on the assembly line when configuring laser cutting machines, due to limitations of weight, structure and other factors. When the material reaches the position of the laser cutting machine, it is necessary to stop the movement of the assembly line so that the material can be stopped so that it can be cut easily. Cutting cannot achieve continuous feeding
